Abstract

A cylinder comprises a cylinder body, a main cavity body, a piston and a piston rod. Air inlets and air outlets are arranged in each of two opposite ends of the cylinder body. The cylinder is further configured with an anti-collision structure. The anti-collision structure comprises a buffer rod arranged on the piston. The cylinder body defines a receiving hole corresponding to the buffer rod. The receiving hole is configured with a first sealing ring that seals a gap between the buffer rod and the receiving hole. The anti-collision structure has a flexible buffering function and does not generate hard impact. Thus, the cylinder has a low vibration and high stability.
